We Are Stardust

We’re closer than ever before to discovering if we’re not alone in the universe. The host for this episode of Transistor, astrophysicist Michelle Thaller, visits the NASA lab that discovered that meteorites contain some of the very same chemical elements that we contain. Then, Michelle talks to a Vatican planetary scientist about how science and religion can meet on the topic of life beyond Earth.
